Description

The present invention relates to aqueous eyebrow cosmetics and eyebrow cosmetics.

Eyebrow makeup includes coloring to change the color of the eyebrows and styling to straighten or add volume to the eyebrows. Such makeup typically uses liquid or gel eyebrow cosmetics, and coloring and styling can be achieved by applying the cosmetics to the eyebrows using an applicator with a coil-shaped (screw-shaped) or comb-shaped applicator.

Liquid or gel eyebrow cosmetics are often water-based due to their quick-drying properties, and contain a film-forming agent such as an aqueous polymer as an ingredient that provides styling effects (see, for example, Patent Document 1 below).

Japanese Patent Application Publication No. 10-287523

In recent years, eyebrow makeup has become more diverse, and one well-known example is makeup that uses techniques such as soap blow-drying to make eyebrows stand upright. This type of makeup requires both the ability to hold the eyebrows in a standing position (setting power) and the ability to keep them in place (keeping power).

However, no eyebrow cosmetics have been developed that can achieve a natural finish while satisfying the above requirements. Conventional eyebrow cosmetics struggle to achieve the setting and staying power required for the above-mentioned makeup, and attempts to increase the setting and staying power tend to impair quick-drying properties and make it difficult to achieve a natural finish. For example, aqueous cosmetics containing a high content of film-forming agents such as aqueous polymers tend to feel sticky from application until they dry, and become stiff after drying. Furthermore, repeated combing with a comb-shaped applicator during the setting process can cause flaking, which causes the eyebrows to turn whitish, or can cause the eyebrow hairs to bunch together, resulting in an unnatural finish.

The present invention was made in consideration of the above circumstances, and aims to provide a water-based eyebrow cosmetic and eyebrow makeup that have the setting and retention power to keep eyebrows standing up, yet dry quickly and produce a natural finish.

In order to solve the above problems, the present invention provides an aqueous eyebrow cosmetic comprising (A) a clay mineral, (B) a film-forming polymer emulsion, and (C) water, wherein the content of component (A) is 5 to 20% by mass based on the total amount of the aqueous eyebrow cosmetic, the glass transition temperature of the polymer in component (B) is -20°C or higher, and the content of component (C) is 30% by mass or higher based on the total amount of the aqueous eyebrow cosmetic.

By having the above-mentioned composition, the aqueous eyebrow cosmetic of the present invention has the setting and hold power to keep eyebrows standing up, while also having excellent quick-drying properties. Furthermore, it prevents eyebrows from turning whitish or sticking together when using an applicator, achieving a natural finish.

The inventors speculate that the reason for this effect is as follows: By blending a specific amount of clay mineral into an aqueous cosmetic containing a specific film-forming polymer emulsion, water is quickly released via the clay mineral upon application, allowing the applied film to dry without becoming sticky, and it is thought that this makes it possible to achieve high setting and hold power while suppressing the stiffness, whitening, and clumping of eyebrows that can be caused by the film-forming agent described above.

One method of eyebrow makeup involves using a pencil-type eyebrow cosmetic, such as an eyebrow pencil, in combination with a liquid or gel-type eyebrow cosmetic that has a styling effect to color and style the eyebrows. In this case, to prevent the styling from coming undone, the eyebrow cosmetic is applied to the eyebrows after using the eyebrow pencil. In contrast, the aqueous eyebrow cosmetic of the present invention can give the eyebrows a flexible finish with high setting power, so the styling is less likely to come undone even when styled eyebrows are drawn with a pencil-type eyebrow cosmetic. Therefore, the aqueous eyebrow cosmetic of the present invention can be used regardless of the order in which makeup is applied, which also has the advantage of making it easy to adjust the finish of eyebrow makeup.

The aqueous eyebrow cosmetic of the present invention contains, as component (A), a clay mineral (A1) having a viscosity of 5,000 mPa·s or more at 25°C when made into a 4% by mass aqueous solution, and the content of component (A1) may be 10% by mass or more based on the total amount of component (A).

The content of component (B) may be 0.3 to 5.0 mass% in terms of solid content, based on the total amount of the aqueous eyebrow cosmetic.

Furthermore, the mass ratio [(A)/(B)] of the content of component (A) to the content of component (B) converted to solids may be 1.8 or greater.

The present invention also provides an eyebrow cosmetic comprising the aqueous eyebrow cosmetic of the present invention contained in a container and an applicator having a coil-shaped or comb-shaped applicator body.

The content of component (A2) may be 0.1 to 20% by mass, 0.5 to 15% by mass, or 1 to 10% by mass, based on the total amount of the cosmetic.

The (A) component can be used alone or in combination of two or more types. Furthermore, the (A1) component and the (A2) component can each be used alone or in combination of two or more types.

The aqueous eyebrow cosmetic of this embodiment may contain component (A1) and component (A2) as component (A). In this case, the blending ratio (A1)/(A2) of component (A1) to component (A2) may be 1/100 to 100/1 from the viewpoint of facilitating non-sticky application, or 1/9 to 100/1, 3/7 to 50/1, or 1/1 to 10/1 from the viewpoint of achieving a natural finish and quick drying.

From the viewpoint of achieving a natural finish and quick drying, the aqueous eyebrow cosmetic of this embodiment may contain, as component (A), a clay mineral (A1-1) with a viscosity of 5,500 to 40,000 mPa·s and a clay mineral (A2-1) with a viscosity of 50 to 4,000 mPa·s in a mass ratio of (A1-1)/(A2-1) of 1/1 to 10/1, or a clay mineral (A1-2) with a viscosity of 6,000 to 30,000 mPa·s and a clay mineral (A2-2) with a viscosity of 100 to 3,000 mPa·s in a mass ratio of (A1-2)/(A2-2) of 1/1 to 10/1.

Note that alkyl acrylates here also include alkyl methacrylates. Component (B) can be used in water as a medium with a solids concentration of 30 to 60% by mass.

The glass transition temperature of the polymer is -20°C or higher, or alternatively -15°C or higher, or even 0°C or higher, from the viewpoints of achieving sufficient setting power, staying power, quick drying, and a natural finish; and from the viewpoints of a natural finish and ease of pencil application after application, it may be 50°C or lower, or alternatively 45°C or lower. The glass transition temperature of the polymer is determined by DSC measurement.

The emulsion particle size of component (B) may be 10 to 150 nm, or even 10 to 100 nm, from the viewpoint of achieving sufficient setting power, hold, quick drying, and a natural finish. Furthermore, if the emulsion particle size of component (B) is 30 to 90 nm, the aqueous eyebrow cosmetic is less likely to become white even when applied multiple times. The emulsion particle size is measured using a dynamic light scattering particle size distribution analyzer (for example, LB-550, manufactured by Horiba, Ltd.).

Component (B) can be a commercially available product such as "DAITOSOL 3000SLPN," "DAITOSOL 3000VP3," "DAITOSOL 4000SJT," or "DAITOSOL 5000AD" (all trade names manufactured by Daito Kasei Kogyo Co., Ltd.), "YODOSOL GH800" or "YODOSOL GH800F" (all trade names manufactured by Akzo Nobel), or "COVACRYL MS11" (trade name manufactured by SENSIENT).

The content of component (B) in the aqueous eyebrow cosmetic may be 0.3 to 5.0% by mass, 0.5 to 4.0% by mass, or 1.0 to 3.0% by mass, calculated as solids content, based on the total amount of the cosmetic, from the standpoint of achieving sufficient setting power, staying power, quick-drying properties, and a natural finish.

In the aqueous eyebrow cosmetic of this embodiment, the mass ratio [(A)/(B)] of the content of component (A) to the content of component (B) converted to solids may be 1.8 or more, 2.0 or more, 2.5 or more, 25 or less, 20 or less, or 16 or less.

The content of water (component (C)) is 30% by mass or more based on the total amount of the cosmetic, but from the perspective of quick-drying properties, it may be 40-90% by mass or even 50-80% by mass.

The aqueous eyebrow cosmetic of this embodiment may further contain, in addition to water, a lower alcohol having 1 to 5 carbon atoms, such as ethanol. In this case, the content of the lower alcohol may be 1 to 10% by mass, or 3 to 7% by mass, based on the total amount of the cosmetic.

The aqueous eyebrow cosmetic composition of this embodiment may contain a coloring material to achieve a coloring effect. Examples of coloring materials include color pigments, water-soluble dyes, and glitter powders. One or more coloring materials may be used.

Coloring pigments include inorganic coloring pigments such as red iron oxide, yellow iron oxide, black iron oxide, titanium oxide, carbon black, cobalt oxide, chromium oxide, ultramarine, Prussian blue, and zinc oxide; organic coloring pigments such as Red No. 228, Red No. 226, Blue No. 404, Red No. 202, and Yellow No. 4 aluminum lake; and natural dyes such as carmine. Water-soluble dyes include organic dyes such as Red No. 227, Blue No. 1, Yellow No. 4, and Yellow No. 5; and natural dyes such as safflower. Lustrous powders include titanium oxide-coated mica (titanium mica), iron oxide-coated mica, iron oxide-coated mica titanium, organic pigment-coated mica titanium, titanium oxide-coated glass powder, titanium oxide-iron oxide-coated glass powder, and aluminum powder.

The aqueous eyebrow cosmetic of this embodiment may contain a coloring material in an amount of less than 1%, less than 0.5%, less than 0.2%, or less than 0.1% of the total amount of the cosmetic. In this case, the aqueous eyebrow cosmetic can be used as a transparent eyebrow styling agent. Furthermore, the aqueous eyebrow cosmetic of this embodiment can give eyebrows a soft finish with high setting power, so the styling is less likely to come undone even when styled with a pencil-type eyebrow cosmetic (in other words, it is easy to draw with a pencil after application). This allows for coloring with an eyebrow pencil or the like after styling, if necessary.

The aqueous eyebrow cosmetic of this embodiment may contain fibers to achieve a volume-enhancing effect. Examples of fibers include nylon fibers, rayon fibers, polypropylene fibers, polyester fibers, and cellulose fibers. There are no particular restrictions on the length of the fibers, but generally, 0.1 to 10 mm is preferred, and 0.3 to 7 mm is more preferred. The thickness of the fibers is generally preferably 0.1 to 25 tex (hereinafter simply referred to as "T"), and more preferably 0.3 to 20T. There are no particular restrictions on the cross-sectional shape of the fibers. One or more of these fibers with different materials, thicknesses, and lengths can be used.

In addition to the above-mentioned components, the aqueous eyebrow cosmetic of this embodiment can also contain other components commonly used in cosmetics, such as surfactants, film-forming agents other than component (B), powder components other than the pigments and fibers mentioned above, moisturizers, viscosity adjusters, preservatives, pH adjusters, chelating agents, UV absorbers, vitamins, cosmetic ingredients, antioxidants, fragrances, etc., as needed, within a range that does not impair the effects of the present invention.

From the standpoint of quick-drying properties, the aqueous eyebrow cosmetic of this embodiment may contain no more than 1% by mass, no more than 0.5% by mass, no more than 0.3% by mass, or no more than 0.1% by mass of polysaccharide thickener, based on the total amount of the cosmetic, or may not contain any polysaccharide thickener. According to the aqueous eyebrow cosmetic of this embodiment, even when no polysaccharide thickener is blended, separation or precipitation can be sufficiently suppressed. Therefore, by limiting the amount of polysaccharide thickener, which tends to be sticky, quick-drying properties and storage stability can both be achieved.

Because the aqueous eyebrow cosmetic of this embodiment has sufficient quick-drying properties, the content of volatile components (excluding water) may be 10% by mass or less, 7% by mass or less, or 5% by mass or less, based on the total amount of the cosmetic, or the cosmetic may contain no volatile components (excluding water).

From the standpoint of storage stability, the aqueous eyebrow cosmetic of this embodiment may have an oily component content of 5% by mass or less, or 1% by mass or less.

From the standpoint of setting power and a natural finish, the aqueous eyebrow cosmetic of this embodiment may have a consistency of 0.2 to 1.2 N, or 0.3 to 0.9 N. The consistency of the cosmetic is determined by the following measurement method.

<Method for measuring consistency>
A measurement sample is prepared by filling a 30 mL screw cup with the cosmetic material and leaving it overnight (24 hours) at 25° C. The consistency of this measurement sample is measured at 25° C. using a FUDOH rheometer RT-2002D.D (manufactured by Rheotec Co., Ltd.) with a pressure-sensitive shaft of 10φ sphere, a penetration speed of 6 cm/min, and a penetration depth of 10 mm.

The aqueous eyebrow cosmetic of this embodiment can be produced by dissolving or dispersing the above-mentioned components (A), (B), and (C), as well as other components as necessary, and then stirring and mixing them uniformly. A disper can be used, for example, for stirring and mixing.

The aqueous eyebrow cosmetic composition of this embodiment can be applied to eyebrows using, for example, an applicator with a coil-shaped or comb-shaped applicator body, to achieve a styling effect and, if necessary, a coloring effect, allowing for eyebrow makeup. The aqueous eyebrow cosmetic composition of this embodiment can be used as an eyebrow gel or eyebrow mascara.

The eyebrow cosmetic product of this embodiment may include the aqueous eyebrow cosmetic of this embodiment contained in a container and an applicator having a coil-shaped or comb-shaped applicator body.

Examples of coil-shaped or comb-shaped applicators include wound brushes, combs, and bristles.
